Two Swords is the first, spectacular, episode of Game of Thrones Season 4 and it's already been screened in the US and very early this morning on Sky Atlantic HD (and in SD). It is also being repeated tonight in its traditional UK slot of 9pm on the Sky Atlantic channels.

However, if you don't have Sky's satellite service and rightfully refuse to head down the less salubrious stealy web route, you might be wondering how you can see the show this evening.

So we list ways to do just that. In fact, you can even catch the entire episode without having to wait. And it's all above board.

NOW TV

With a £4.99 a month NOW TV Entertainment Pass you can watch Sky Atlantic live tonight (or at any other time) alongside a range of other channels, Sky and otherwise. That means you can watch Two Swords as it airs in its normal slot. However, you can also watch it on demand on the service now, prior to its second showing, as it was originally broadcast at 2am to match the time of the first broadcast on HBO in the US. And NOW TV catch-up is devoid of adverts, so you can jump straight into an uninterrupted version.

NOW TV can be viewed through a dedicated NOW TV box, available for £9.99, Roku media streaming boxes or online through a browser. Apps are also available for iOS, Android, PS3, Xbox 360, and select LG Smart TVs.

The £4.99 a month introductory price is available to those who sign up before 29 May. You can find out more at nowtv.com.

Sky Go

Sky Go already has the episode available for catch-up (preceded by a minute of adverts), but you might be wondering why we include this option considering that you need a Sky subscription to access the app for iOS, Android and Xbox 360.

Well, technically you can subscribe to Sky Go if you're not an existing Sky customer. For £15 a month for a Sky Go Monthly Ticket you can have access to the broadcaster's entertainment channels through Sky Go, which includes Sky Atlantic, on a laptop, desktop computer, smartphone or tablet. However, at £4.99 a month, NOW TV is a better option and is available on all the same devices and more.

Where Sky Go comes into its own is if you have a parent or friend with a Sky subscription and they have no interest in registering their free Sky Go accounts on mobile devices. You could ask if they would let you use one of the device slots instead (you can register up to two devices on one account). They might even let you take up a device slot for the duration of Game of Thrones Season 4 and you can deregister it after.

Alternatively, if they subscribe to Sky Go Extra or you upgrade them to Sky Go Extra for £5 a month, you can take one of four device slots.

The only issues with this method is that the picture quality through Xbox 360 is not as good as NOW TV or TV broadcast, and the iPad app won't allow AirPlay mirroring or direct connection to get the pictures onto a TV. In this case, you really do get what you paid for.

A Storm of Swords

The third and last option is to dispense with watching the episode entirely and sitting down with the book that inspired it. Season 4 is mostly based on the second half of George R R Martin's A Storm of Swords, the third in his series of fantasy novels.

However, producers for the HBO series have revealed that there has been a lot of deviation from the source material this time around, so things might happen differently on the show. The chances of getting away with winging it during conversations down the pub having only read the book are slim.
